T. Shimizu et al., MUSCLE SYMPATHETIC-NERVE ACTIVITY DURING APNEIC EPISODES IN PATIENTS WITH OBSTRUCTIVE SLEEP-APNEA SYNDROME, Electroencephalography and clinical neurophysiology, 93(5), 1994, pp. 345-352
Muscle sympathetic nerve activity (MSNA) was recorded from peroneal ne
rve in 4 OSAS patients during sleep. During apneic episode, MSNA was e
nhanced, but it did not increase progressively toward the end of the a
pneic episode. MSNA remained at a stable level in the later part of an
apneic episode. A surge of MSNA took place just preceding or just at
the end of an apneic episode and it was followed by a transient marked
blood pressure elevation.
